POCKET FLASH-LIGHT.

Specification of Letters Patent.

Patented May 30, 1916.

To all whom it may concern:

Be it known that I, ANKER S. LYHNE, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Pocket Flash-Lights, of which the following is a specification.

This invention relates to the class of pocket flash-lights commonly known as pistol flash-lights, from the fact that the case is shaped to more or less closely resemble an automatic pistol, and the invention has for its object to simplify and cheapen the construction while at the same time making it strong and durable, and to generally improve the operation in use.

With these and other objects in view I have devised the novel pocket flash-light which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is an elevation showing the case opened to expose the operative parts, which are in the normal or open circuit posltion; Fig. 2 a similar view showing the parts in the operative or closed circuit position; Flg. 3 a detail view on an enlarged scale partly in section showing the construction of the movable contact by which the circuit is closed; Fig. 4 a section on the line 44 in Fig. 3, looking in the direction of the arrows, and Fig. 5 is a section on the line 5-5 in Fig. 3, looking in the direction of the arrows.

The case consists of two corresponding sheet metal parts indicated respectively by and 11, which are hinged together at the bottom of the handle portion.

12 denotes a dry cell battery which is socketed in the handle portion of the case and is provided with terminals 13 and 14. Terminal 13 has interlocking engagement with a notch 26 in a supporting strip 15 secured to the case. This interlocking engagement of the terminal and supporting strip electrically connects the battery w1th the case and serves in connection with a plate as a means for detachably retaining the battery in place.

16 denotes an electric lamp which is detachably secured at the forward end of the barrel portion of the case. In the present instance I have shown all the operative parts as carried by part 10 of the case.

17 denotes the center contact of the lamp which is adapted to be engaged by a movable contact 18 rigidly secured to a trigger 19, but insulated therefrom, as clearly shown, the insulation being indicated by 20. The trigger is protected by a guard 21 and is normally retained in the inoperative or open circuit position by a spring 22. The movable contact comprises arms 23 and 24 which are adapted to engage respectively the center contact of the lamp and battery terminal 14 to close the circuit, as clearly shown in Fig. 2, said contact arm and terminal being suitably shaped to insure a wiping engagement when the trigger is moved to the closed circuit position as in Fig. 2.

The operation will be obvious from the drawing. The spring normally retains the trigger and movable contact in the open circuit position. To close the circuit and flash the lamp, the operator pulls the trigger and carries the movable contact from the position shown in Fig. 1 to that shown in Fig. 2. The instant pressure upon the trigger is relieved, the circuit is opened again by the action of the spring.

Having thus described my invention I claim 1. A flash-light comprising a case adapted to carry an electric lamp and a dry cell battery, a trigger pivoted to the case and a movable contact rigidly secured to the trigger but insulated therefrom and adapted to be moved into engagement with a battery terminal and the center contact of the lamp.

2. A flash-1ight comprising a case adapted to carry an electric lamp and a dry cell battery, a movable contact adapted to simultaneously engage a battery terminal and the center contact of the lamp and means for normally retaining said contact in the open circuit position.

3. A flash-light comprising a case adapted to carry an electric lamp and a dry cell battery, a movable contact adapted to simultaneously engage a battery terminal and the center contact of the lamp, a spring for normally retaining said contact in the open circuit position and means for moving said contact to the closed circuit position.

4. A flash-light comprising a two-part case, one of said parts being adapted to carry an electric lamp and a dry cell bat tery, a trigger pivoted to said part and a movable contact rigidly secured to the trigger but insulated therefrom and adapted to simultaneously engage a battery terminal and the center contact of the lamp. 5. In combination in a flash-light, a case aving a notched supporting strip, an electric lamp, a dry cell battery having terminals, one of which has interlocking engagement with the supporting strip, a movable contact adapted to simultaneously engage the other battery terminal and the center contact of the lamp, and means for normally retaining said contact in the open circuit position.

6. In combination in a flash-light, a case having a notched supporting strip, an electric lamp, a dry cell battery having terminals, one of which has interlocking engage ment with the supporting strip, a movable contact adapted to simultaneously engage the other battery terminal and the center contact of the lamp, an insulating trigger by which said contact is carried and a spring for normally retaining said trigger an contact in the open circuit position.

A flash-light comprising an exterior casing composed of two longitudinal hollow shells imitating the handle and barrel portions of a pistol, a trigger carried by one of said shells, an electric lamp in said barrel portion, a battery in said handle-portion having one terminal in engagement with said casing, and a contact-conductor on said trigger having one end to engage the other battery terminal and its other end to engage the lamp-terminal when the trigger is pulled.

8. A flash-light comprising an exterior casing composed of two substantially corresponding matching longitudinal hollow shells imitating the two vertical longitudinal halves of the handle and barrel portions of a pistol and adapted to be opened outwardly from each other, a trigger carried by one of said shells, an electric lamp in said barrel portion, a battery in said handle portion having terminals, and a contactconductor on said trigger having one end to engage one of said terminals and the other end to engage the lamp-terminal when the trigger is pulled.

9. A flash-light comprising an exterior casing composed of two substantially corresponding matching longitudinal hollow shells imitating the two vertical longitudinal halves of the handle and barrel portions of a pistol and adapted to be opened outwardly from each other, a trigger carried by one of said shells, an electric lamp in said barrel-portion, a battery within said casing having one terminal in electrical engagement therewith, and a contact-conductor operable on the pull of said trigger to connect the other battery-terminal with the lamp.

In testimonywhereof I afiix my signature in presence of two witnesses.
